ME TOO!!!! I have a 3 month old EB, and he is the same way. He whines to go outside, but he gets these random episodes of aggression too. Like if we are sitting on the couch, or not doing what he wants to do he starts barking at us, or trying to bite at us (he is trying to bossy, it's not the normal puppy hyperness). I feel like he is depressed or something weird (I wrote a post about it actually). He wants to play, but can't get past trying to bite....all the good old tricks don't work with him either. Like ignoring him....he either barks at us, or goes some where and pouts all day (but it has no effect on him). Giving him a toy....he plays with it for like 10 seconds and then goes back for the hands. We've tried to be stern (talking in a stern voice, etc.), and that doesn't work with him and just seems to make him even more aggressive. We tried a time out last night, and that didn't have any impact either....he got out and was just ticked off at us, not actually sorry for what he did.
I really have noticed that with my EB he is hard to train because although he does care about us, if he gets any discipline he gets mad at us, instead of realizing that he can't nip, and bark at us.
Maxwell has been REALLY good about house training (he is pretty much totally house trained at only 3 months), but the whole nipping thing and aggression out of no where is getting really annoying. He is very lovey dovey a lot of the time, and is just fabulous with our daughter.....but then he just gets these streeks of attitude. We have been more on him about trying to stop the bad behaviours this week, and I honestly think he's just getting depressed about it or something odd.
We start an obedience class in a couple weeks here...I hope this trainer is GOOOOOOOD, because Max definetly has his own mind!!!!!
Feel free to message me!!!!!
